Abstract (en)
[origin: US4695411A] The invention concerns a process for manufacturing a composition of fatty acid esters useful as gas oil substitute motor fuel, said composition containing at least one hydrated ethyl alcohol. The process comprises: (A) A first acid transesterification step in the presence of at least one aliphatic, linear or branched monoalcohol of 1 to 5 carbon atoms, consisting at least partly of hydrated ethyl alcohol containing 1 to 60% by weight of water, said step leading to the formation of a phase mainly containing ethyl esters after removal of the produced glycerol phase, (B) A second step wherein the initial free acidity or that formed during the first step in the phase containing the esters is decreased to a value at most equal to about 2%; and (C) A third step of basic transesterification of the phase resulting from step B, in the presence of at least one aliphatic, linear or branched monoalcohol of 1 to 5 carbon atoms, with the recovery of the so-formed ester composition. The composition of the invention can be used for combustion in Diesel engines.
